Study Lenses
The verse centers on "faith", "peace", "brethren", "love", "father", "lord", "jesus", and "christ". It is saying that the verse draws attention to "faith" and "peace", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 22's "whom I have sent to you for..." into verse 24's "Grace with all them that love our...", so "faith" and "peace" belong inside that flow. In Ephesians context, the local focus is grace, union with Christ, the church, and new creation.
A plain takeaway is to answer the verse's own emphasis on "faith" and "peace" with trust shaped by these words, not by a vague optimism outside the passage.
